Mean : 
Standard deviation : 
Let X be a random variable that represents the heights of adult males in the United States .
Z-score : 
(a) For x= 64

For x= 74

Using the standard normal distribution table , we have
The deviation 2.8 inches. (a) What is the probability that an adult male chosen at random is between 64 and 74 inches tall :-

Hence, the probability that an adult male chosen at random is between 64 and 74 inches tall = 0.927
b) Since 1 feet = 12 inches
Then , 6 feet = 
The z-score corresponds to x=72 :

Then , the probability that the adult male population is more than 6 feet tall :-

Hence, the percentage of the adult male population is more than 6 feet tall = 14.2%
